Сonverter DN-3 piezoelectric vibration measurement (hereinafter vibrator) is designed to convert mechanical vibrations into electrical signals proportional to the acceleration of the vibrating object.

Vibrator DN-3 is used in conjunction with vibration measuring devices to measure vibrations in the plant or in the laboratory. Vibrator is a nd a beautiful complex.

Operating conditions vibrator DN-3: temperature from 243K to 343K (from -30 ° C to 70 ° C), (when fixing the wax to a temperature of 313 K (40 ° C), relative humidity of 90% at an ambient temperature of 300 K (plus 27 ° C), acoustic noise up to 140 dB, and the value of the inverter output voltage in the frequency range of 200-4000 Hz, less than 2.5 mV external magnetic field strength of 400 A / m, the output voltage of the inverter is not more 50 mV, the acceleration shock of 5000 m / s, the pulse duration within 0,015-12,5 ms.

Capacitance vibrator DN-3 cable is not less than 1100 pF. The nominal value of the conversion factor vibrator at a frequency of 1000 Hz, 10 (2 mV · s) / m The actual value of the conversion factor vibrator does not differ from the nominal by more than ± 10%.

Frequency response DN-3 relative to the output signal level at 1000 Hz in the frequency range from 1000 to 4000 Hz is not more than ± 10%.

The relative ratio of the cross conversion no more than 5%. Amplitude linearity up to 1200 m / s 2 is not more than ± 10%. Vibrator change the conversion factor with respect to the conversion efficiency is normally not more than ± 0,3% / ° C.

Overall dimensions of the vibrator DN-3 (without cable): 22h28h24 mm.
Mass vibrator (without cable and connector) is not more than 0,059 kg.
